Cov khoom siv raw

Cov khoom siv tseem ceeb rau kev tsim cov xim av fused alumina yog bauxite, cov ntxhia uas nws lub ntsiab yog aluminium hydroxide. Lwm cov khoom siv raw uas tuaj yeem siv rau hauv cov txheej txheem tsim muaj xws li thee, hlau filings, thiab sawdust.

 

Kev Tswj Xyuas Zoo

Txhawm rau kom ntseeg tau qhov zoo ntawm cov xim av fused alumina, ntau qhov kev tswj xyuas zoo tau siv thaum lub sijhawm tsim khoom. Cov kev ntsuas no suav nrog kev saib xyuas qhov kub thiab txias ntawm qhov cub, kuaj cov tshuaj lom neeg ntawm cov khoom, thiab tshuaj xyuas qhov loj thiab cov duab ntawm cov khoom.

 

Kev siv ntawm Brown Fused Alumina

 

Xim av fused alumina abrasive

yog ib qho kev siv abrasive, dav siv hauv sandblasting, sib tsoo, thiab txiav. Nws lub siab hardness thiab durability ua rau nws zoo tagnrho rau tshem tawm cov txheej txheej thiab rau saum npoo kev kho mob ua ntej painting los yog lwm yam txheej txheem.

 

Brown fused alumina kuj tseem siv los tsim cov khoom siv refractory

uas yog siv los ua cov ntaub rau cov qhov cub thiab lwm yam khoom siv kub -. Nws qhov siab melting point thiab thermal shock kuj ua rau nws zoo tagnrho rau cov ntawv thov no.

 

Kev kho saum npoo

Ntxiv rau nws siv los ua ib qho abrasive, xim av fused alumina yog siv rau kev kho deg hauv ntau yam lag luam. Nws tuaj yeem siv rau roughen nto los txhim kho adhesion, los yog ntxuav thiab npaj cov chaw rau kev ua haujlwm tom ntej.

 

Brown fused alumina kuj muaj lwm yam kev siv dav, xws li hauv kev tsim cov ceramics, polishing compounds, thiab vuam electrodes.

 

Qhov zoo ntawm Brown Fused Alumina

 

Durability thiab Hardness

Brown fused alumina yog cov khoom siv ruaj khov thiab tawv, muaj peev xwm tiv taus kev siv hnyav thiab rov cuam tshuam tsis tau tawg lossis tawg.

 

Chemical Stability:

Brown fused aluminaCov tshuaj muaj kev ruaj ntseg zoo thiab tsis cuam tshuam los ntawm cov kua qaub, alkalis, lossis lwm yam corrosive. Qhov no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau qhov hnyav hnyav.

 

 

Tsawg Thermal Conductivity: Brown fused alumina muaj cov thermal conductivity tsawg, txhais tau tias nws tsis zoo ntawm kev hloov cua sov. Cov cuab yeej no ua rau nws tsim nyog rau cov ntawv thov uas yuav tsum tau tswj qhov kub thiab txias, xws li kev tsim cov khoom siv refractory.

 

Qhov tsis zoo ntawm Brown Fused Alumina:

 

Kev cuam tshuam ib puag ncig: Kev tsim cov xim av fused alumina muaj kev cuam tshuam ib puag ncig vim nws yuav tsum tau bauxite mining thiab siv ntau lub zog thaum ua haujlwm. Txawm li cas los xij, kev ntsuas tuaj yeem txo qis qhov cuam tshuam no, xws li siv cov khoom siv rov ua dua tshiab thiab txhim kho kev tsim khoom.

 

Piv rau lwm cov ntaub ntawv,

xim av fused alumina tej zaum yuav kim dua lwm yam abrasives, xws li silicon carbide los yog alumina. Txawm li cas los xij, nws cov kav ntev thiab lub neej ua haujlwm ntev ua rau nws tus nqi - xaiv tau zoo hauv qee yam kev siv.

 

Hom Brown Fused Alumina:

Kev faib tawm los ntawm Loj thiab Zoo: Xim av fused alumina muaj nyob rau hauv ntau qhov ntau thiab tsawg thiab cov duab, suav nrog angular, blocky, thiab puag ncig. Qhov kev xaiv ntawm particle loj thiab cov duab yog nyob ntawm daim ntawv thov tshwj xeeb.

 

Kev faib tawm los ntawm Chemical Composition: Brown fused alumina tuaj yeem raug cais raws li nws cov tshuaj muaj pes tsawg leeg. Cov qib sib txawv ntawm impurities tuaj yeem cuam tshuam rau cov khoom siv thiab kev ua haujlwm hauv kev siv sib txawv.

 

Xaus: Hauv cov ntsiab lus, xim av fused alumina yog cov khoom siv ntau yam nrog ntau hom kev lag luam. Nws lub siab hardness, durability thiab tshuaj stability ua rau nws yog ib qho zoo tagnrho xaiv rau zus tau tej cov abrasives, refractory cov ntaub ntawv thiab kho deg.
